From the investigation

Altitude: product governance and correction boundaries

Observed 9 September 2026. This is a bounded static inspection of the public implementation linked by Tech Against Terrorism (TAT), not an installed or deployed system test. Acquisition is closed. No product/API calls, accounts, forms, content feeds, terrorist-content files, dependency installation or repository test suite were used. Canonical cases, readers and ZIPs were untouched.

Finding that changes the map

A publicly released departmental status document records Canada partnering with Tech Against Terrorism to formally launch TCAP 2.0 at the Canada Centre's event of 1–5 May 2023. This earns a dated government participation/delivery relation. It does not establish acceptance of either grant workstream, completion of Phase 2, a contractual milestone, or authorization/payment of a particular instalment.

Tech Against Terrorism: the verifier, its legal controller and its operating rules

The strongest new relationship is concrete corporate and financial dependence: Tech Against Terrorism (TAT) is implemented by Online Harms Foundation (OHF); OHF's filed controlling entity is QuantSpark Limited; OHF also reports receiving loans from, being invoiced by, and owing money to QuantSpark. A separate official Canadian award directly funds development of the Terrorist Content Analytics Platform (TCAP). Neither record gives a donor a demonstrated right to order an individual content classification.
